Pressure Tech™ Test Sub

Robust, ball-activated drillpipe flex sub

The CleanWell® Pressure Tech™ test sub is designed to allow drillpipe to be flexed and shocked, assisting with cement sheath, scale or debris removal. Often the same drillpipe on the rig is used when running and cementing the liner for the displacement. Rather than introducing and handling residual debris throughout the displacement, the Pressure Tech test sub allows the string to be flexed and shocked, allowing debris to be reversed out to surface.
